Abstract
A process for the preparation of 1,4-dihydropyridine derivatives according to the formula: * (see formula 1) * in which R1 is phenyl which can have one or more appropriate substituents selected from halogen and nitro, R2 and R3 are each, the same or different, esterified carboxy, and one between R4F and R5f is methyl and the other is (C2-10) acyl oxyalkyl.
